registers (D1350, D1351) corresponding to CH1 pulse, so it is recommended to use these two
registers. If other registers are used, the data will need to be transmitted into the current value
registers (D1348, D1349) corresponding to CH0 pulse or the current value registers (D1350,
D1351) corresponding to CH1 pulse.
7. When the DABSR instruction is enabled and reading starts, the command execution
completed flag M1029 will be ON. The flags must be reset by the user.
8. When executing the DABSR instruction, use a normally open contact. If the contact of DABSR
command turns OFF when DABSR command read starts, the execution of the absolute
current value read will be interrupted and result will be incorrect.
9. If the DABSR instruction is disabled after the read is complete, the Servo ON (SON) signal
connected to D
1
will also turn OFF and the operation will be disabled.
Program Example:
1. When X7= ON, the absolute position data (32 bit) read from Servo should be stored in the
current value register (D1348, D1349) corresponding to the CH0 pulse. At the same time, use
a timer T0 to time for 5 seconds. If the time exceeds 5 seconds and the absolute position data
(32 bit) read is not complete, M10=ON and this means the absolute position data (32 bit) read
is abnormal.
2. When connecting to the system, set the power of ELC-PV series and SERVO AMP to be ON
at the same time or set the SERVO AMP to be ON before power is applied to ELC.
